Solar Kid or TS-MPPT? Which one?

So I am putting together a solar electric system that will use 3 270 watt panels to get 810 watts total and those panels will be used to charge a series parallel 24V/460AH bank of four 6 volt titan 105’s. I now need to make a decision on a charge controller. I have narrowed it down to either the Midnite Solar Kid or the Morning Star TS-MPPT-45 but would appreciate any other suggestions as well as any input on experiences using these two units.

I would prefer the TS-MPPT-45, just because, as one of our former moderators was fond of saying "Loads grow" and so do system, it would be nice to have the extra room to add some panels.

Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites, Midnite E-panel, Prosine 1800 and Exeltech 1100, ForkLift battery. Off grid for @13 of last 14 years. 1000 watts being added to current CC, @2700 watts to be added with an additional CC.

I was thinking series & parallel with 4 6V 220AH Trojan's for a 24V 440AH output. So by "loads grow" you mean get an over sized charge controller? The Midnite allows you to run multiple units as the system load increases.

If they are in series +6-+6-+6-+6- = 24 volts @ 220 aamphours

If they are in series and parallel +6-+6-+< >- = 12 volt @ 440 amp hours +6-+6-

At 12 volts, the array might fit on a Morning Star TS-MPPT-45 but you would be better off going to a 60 amp charge controller

At 24 volts, either would work x2 the voltage = 1/2 the ampsamps x volts =wattswatts/amps=voltswatts/volts=amps

I don't think his balance of panels to battery bank is bad here, I suspect we have the battery count correct at 4, just not the correct amp hour rating.
